UNSPSC 51286804: Proquinolate

This classification denotes an antimicrobial with the molecular formula C17H21NO5, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 5M91328O79, chemically known as 3-quinolinecarboxylic acid, 4-hydroxy-6,7-diisopropoxy-, methyl ester but more generally known as proquinolate, which bears US NIH Compound Identifier 15547. European Medicines Agency schedules Proquinolate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10128MIG.

The term PROQUINOLATE is an International Non-Proprietary Name or INN (see World Health Organization INN reference publication, Volume 21 No. 12 1967, List 7). PROQUINOLATE is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: O(C1C(OC(C)C)CC2[NH]CC(C(=O)C2C1)C(=O)OC)C(C)C.

UNSPSC 51286804 Proquinolate is a Commodity code, but the recent state and local opportunities tagged to it do not reflect purchases of proquinolate itself. Instead, the opportunities show procurement of unrelated pharmaceutical products — naloxone and safe drug deactivation systems through Seminole County, Florida, and doxycycline hyclate and ciprofloxacin through the Illinois Department of Public Health via a piggyback pharmaceutical warehouse contract. The mismatch suggests this code is receiving misclassified submissions or that the tagging does not align with the actual commodity scope. State and local governments do appear to use UNSPSC pharmaceutical codes to solicit emergency-response and public-health pharmaceuticals through county health departments and state public-health agencies, often via competitive bid (IFB) or piggyback arrangements through multi-state cooperative purchasing consortia such as MMCAP. The issuing bodies recorded include state health departments and county community health functions.

Recent activity centers on Florida and Illinois. Seminole County, Florida posted an IFB on June 30, 2026 for naloxone and drug deactivation systems with a response deadline of July 26, 2023 (note: the due date appears to be a data error), calling for 1,900 units of naloxone and 800 deactivation systems annually with quarterly deliveries and potential FEMA funding. The Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical warehouse piggyback contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026 for a 12-month initial term with two renewal options. Without confirmed activity under the proquinolate code itself, assess whether this code genuinely captures the pharmaceutical procurement activity state and local buyers are conducting, or if a code reclassification or cross-reference to broader pharmaceutical Family codes would be more actionable.
